BOB-SLED.

SPECIFICATION forming part of Letters Patent No. 294,883, dated March 1l, 1884.

Application filed January 11,1884.

To all whom, it may concern:

Be it .known that I, J osnrrr H. KIRK, of Brady township, in the county of Clearfield, and State of Pennsylvania, have invented 'cer tain new and useful Improvements in Bob- Sleds, of which the following is a full, clear, and exact description.

Reference is to be had tothe accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a plan view of the forward bob of a sled to which my improvement has been applied. Fig. 2 is a side elevation of the sled. Fig. 3 is an elevation of the jointed king-bolt. Fig. 4 shows amodication of the platform.

The object of this invention is to construct bob-sleds in such amanner that they can adapt themselves to uneven surfaces without throwing undue Strain o n any part of the sled.

rfhe invention consists in a bob-sled constructed with a'platfornror double bolster and a jointed king-bolt, whereby the said bob will be free to move in any direction without affecting the position of the said platform. To the forward bob and its saddle is attached an annular plate, to come in contact with the side bars of the platform and the forward part of the reach-attached to the platform, and limit the rocking and pitching of the said bob, as will be hereinafter fully described.

' A are the beams of the forward bob, which are connected with the runners B by the knees C, and to which the raves D are attached.

To the centersof the beams A is attached the saddle E, the upper side of which is rounded, and to the ends of which and to the raves D is attached the annular plate F. l

Upon the saddle E rests the forward end of the forward part, G, of the reach, which, in connection with thebolsters H and connectingbars I, forms the platform, the bars I serving as stops, against which the plate F at any point of its upper face may strike to limit the rocking and pitching of the bob.

Two or more holsters, H, may be used, and the said bolsters are attached to the forward part, G, of the reach and to the connectingbars I, or the bolster H can be attached to two curved bars, I', attached at their middle (No model.)

parts to the said forward part of the reach, with their ends meeting upon the opposite sides of the said part G of the reach, as shown in Fig. et.

J is the king-bolt, which passes through the forward part, G, of the reach, through the saddle E, and through the beam A, upon which the center of the said saddle E rests. The

' king-bolt .Tis secured in place by nuts screwed upon its ends, and is made in two parts jointed to each other at the point where the forward part, G, of the reach comes in contact withV the saddle E, so that the bob will have a free movement in every direction beneath the platform. l i

The holsters H are provided with stakes K, to keep the forward part of the sled-body L in place, so that the said body will be held at points in front and rear of the king-bolt, and

the body and holsters will be prevented from moving upon veach other.

The rear part of the' sled-body rests upon the bolster M of the rear bob N.

O is the rear part of the reach, which passes through a hole in the bolster M, and is connected with the forward end of the rear bob, N, by a bail, chain, or other suitable connection, I. Several holes are formed in the rear part, O, of the reach, to receive the connection I), so that the sled can be readily lengthened and shortened, as maybe required. The

rear end of the forward part, G, of the reach and the forward end of the rear part, O, overlap each other, and are connected bytwo keepers, Q., and a bolt, R, so that the rear part, O, S5

of the reach can be readily detached and Areplaced by a longer or shorter one, as may be required. V ith this construction the sled is free to adapt itself to an uneven surface, and

can be turned in a very small space without 9o unduly straining'any of its parts.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A bob-sled constructed, substantially as herein shown and described, with a platform or double bolster and a jointed king-bolt, as set forth.

2. In a bob-sled, the combination, with the forward bob, A B C D, having saddle E, and

IOO

the forward part, G, of the reach, of the platform or double bolster H I and the jointed tially as herein shown and described, whereby king-bolt J, substantially as herein shown and the rocking` and pitching of the said bob Will described, whereby the said bob will be free l be limited, as set forth. to move in anT direction Without affecting the 4 A n Y .r position of the said platform, as set forth.
